Red, a former officer of the United States Navy who disappeared twenty years earlier, before becoming one of the FBI Ten Most Wanted Fugitives, surrenders himself to Harold Cooper FBI Headquarters in Washington, D.C. Taken to an FBI "black site", Reddington claims to share the FBI's interest in getting rid of criminals and terrorists he has associated with, that are so dangerous and devious that Cooper is unaware even of their existence. He offers Cooper his knowledge and assistance on two conditions: immunity from prosecution, and working exclusively with Elizabeth Keen, a rookie profiler newly assigned to Cooper. Keen and Cooper are suspicious of Red's interest in her, but he will only say that she is "very special". After Cooper tests Reddington's offer in locating and killing a terrorist in the first episode, Reddington reveals that this man was only the first on his "blacklist" of global criminals, which he has compiled over his criminal career, and states that he and the FBI have a mutual interest in eliminating them. As the series progresses, the mysteries of Reddington's and Liz's lives, and his interest in her, are revealed slowly.
